Embodiment Construction

[0022]This disclosure relates to bifurcation treatment systems, catheter assemblies, and related methods of treating bifurcations in a patient's body. The term bifurcation means a division location from one unit into two or more units. Generally, two types of bifurcations of a body organ include: 1) a main tubular member defining a main lumen and a branch tubular member defining a branch lumen that extends or branches off from the main tubular member, wherein the main and branch lumens are in fluid communication with each other, and 2) a primary or main member defining a primary or main lumen (also referred to as a parent lumen) that splits into first and second branch members defining first and second branch lumens. The term lumen means the cavity or bore of a tubular structure such as a tubular organ (e.g., a blood vessel).

[0023]An example bifurcation is a vessel bifurcation that includes a continuous main vessel and a branch vessel, wherein the vessels define a main lumen and a b...

Abstract

A catheter assembly and related methods for preparing and assembling catheter assemblies. The catheter assembly includes main and side balloons. The main balloon includes side portions that are folded in opposite directions toward a bottom surface of the main balloon to place the main balloon in a folded state. The side balloon is typically positioned along a top surface of the main balloon. The folded balloons can be retained in a folded state with various retaining structures during further preparation and assembling of the catheter assembly.

Description

TECHNICAL FIELD [0001]This disclosure relates to catheter assemblies configured for treatment of a vessel bifurcation, and more particularly relates to catheter balloon folding arrangements and related methods for such catheter assemblies.BACKGROUND [0002]Catheters are used with stents and inflatable structures to treat conditions such as strictures, stenoses, and narrowing in various parts of the body. Various catheter designs have been developed for the dilatation of stenoses and to deliver and deploy stents at treatment sites within the body.[0003]Stents are typically intraluminally placed by a catheter within a vein, artery, or other tubular shaped body organ for treating conditions such as, for example, occlusions, stenoses, aneurysms, dissections, or weakened, diseased, or abnormally dilated vessels or vessel walls, by expanding the vessels or by reinforcing the vessel walls. Once delivered, the stents can be expanded using one or more inflatable members such as balloons. Sten...
